Types

type CardFunc 

type CardFunc func(context.Context, *ent.CardMutation) (ent.Value, error)

The CardFunc type is an adapter to allow the use of ordinary function as Card mutator.

func (CardFunc) Mutate

func (Chain) Append added in v0.1.5 

func (c Chain) Append(hooks ...ent.Hook) Chain

Append extends a chain, adding the specified hook as the last ones in the mutation flow.

func (Chain) Extend added in v0.1.5 

func (c Chain) Extend(chain Chain) Chain

Extend extends a chain, adding the specified chain as the last ones in the mutation flow.

func (Chain) Hook added in v0.1.5 

func (c Chain) Hook() ent.Hook

Hook chains the list of hooks and returns the final hook.
